A to 31.12.1991 and this extension was also approved by the District Inspector of Schools. After the tenure of service ended on 31.12.1991 for some explicable reasons, the respondent no.1 's appointment was extended from 2.1.1992 to 31.3.1992. However, this extension was not approved by the District Inspector of Schools, instead District Inspector of Schools 8 requested the school to take fresh steps to fill in the said vacancy. A fresh advertisement was, therefore, published on 23.2.1992. The respondent no.1 applied and was again selected and he was thus given appointment on the previous C terms for a period from 3.4.1992 to 30.6.1992. On 3. 7.1992, the original incumbent on the post who had gone on leave and in whose place the respondent was appointed resigned and as a result, a substantive vacancy arose in the permanent sanctioned post of Assistant Teacher in Bio Science group. A representation came to be made by the respondent no.1 on D 14.8.1992 that since he had worked in the school as Assistant Teacher on and from 24.1.1991 to 30. 7.1992 on ad hoc basis and since the original incumbent of the post one Shri Shanker Biswas had submitted his resignation, the services of the respondent no.1 should be regularized. A Writ Petition came E to be filed by him on 25.8.1992 registered as CO No.18711 (W) of 1992. Amongst other prayers, the respondent no.1 herein sought his absorption and regularization in the permanent vacancy with effect from his appointment and also sought an injunction against the appellants herein restraining F them from proceeding in any way, in filling up the said vacancy.
